From: Ville Syrjälä <[email protected]> By the time intel_fbc_global_disable() gets called during driver teardown we should have already disabled all the crtcs, so no way FBC should be enabled at this point.
And I have no idea what the other user (i915_restore_display()) is even trying to achieve. So let's just throw intel_fbc_global_disable() into the bin.
